WU gave me KB5014699, and the machine would not boot. This time, I got a BSOD:

WU KB5013942 and .NET update KB5013624 installed yesterday. Computer would not boot, hanging at black screen with ball bearings animation in white near the bottom of the screen, nothing else, for...

I think it's OK. The old Windows 10 is several years old and has had problems from the beginning. Apparently a rescue from disk backup or some such put the Recovery partition at the bottom of the...

You're right, I should have looked up the details before I posted. In addition to Windows.old, restore points are deleted as new ones are established. Windows Update establishes a restore point,...

That "lost 2 GB of space" will probably take care of itself as Windows cleans up after itself. Updates can be removed up to a week or so, after which the files needed for this are removed. You may...

Of course. I use Hard Disk Sentinel to montior SMART data on all my HDs. I run sfc and dism to clean up after every upgrade. I use Dymax IO (successor to Diskkeeper, now it uses RAM as extended...

WU KB5011487 bricked my main Windows 10 machine. Rescue media from previous Windows 10 configurations from build 2004 on failed to repair boot configuration. Log showed an error that a disk was not...

Thank you for getting back to me here. I get help here when I need it and like to give back when I can. It's great to know that I did help someone with a knotty problem. It's also good to learn...

Updated the computer to 21H2 and the dumbed-down Microsoft basic video driver was there. I went through the instructions on the link in post #2, with one major difference: In Device Manager,...

Worked on my laptop OK, but in the process re-installed a downgraded video driver for the built-in ATI Mobility Raedon HD 4250 that is so limited to effectively disable the laptop. The built-in...

Both of them were fine for years. After I turned off sleep and shutdown, they lasted about a year running 24/7. Neither of them were cheap anything.

What has gone on two laptops is the processor or motherboard. The first one lost about half its speed, then the USB ports and the CD-ROM/DVD drive stopped working. The next one started locking up a...

My machine has a processor that is not Windows 11 compliant, AMD FX-8370 (8 threads, 4.3 GHz) and I plan to keep it for many years. After Windows 10 EOL in late 2025, perhaps non-Microsoft...

Installed WU KB5007186, .NET update KB5006365, driver update for cell phone, and malicious software removal tool on my main Windows computer (ASUS 990FX R2, AMD FX-8370, etc.) with known boot...

Installed WU KB5007186 on my old laptop just fine. Printers seem OK, tests OK with B/W laser printer. Canon PRO-100 color ink jet lists "Not available on this device" but Canon app reads ink levels...

Running chkdsk with options /R, /B or /forceofflinefix can take a VERY long time. That's the only way that chkdsk can find and fix bad sectors, though.

You should be able to boot pressing F2 and...

Just installed WU KB5007186 on my old laptop, and it installed just fine, and it works with my KVM switch, and all the graphics resolutions are there. Apparently, the driver rollback to unusability...

I found that the legacy ATI drivers wouldn't work after a certain build, but Microsoft drivers improved to the point that they supported driving projectors and alternate displays, including varying...

I was wondering why I needed to power down my motherboard in order to get the computer to boot.

I use bcdedit on the Recovery media, which are the installation media (DVD or thumb drive). I didn't know that it was available elsewhere until today.

I didn't know that bcdedit.exe was present in a Windows 10 installation. I just booted my old laptop, and I do see that bcdboot.exe and bcdedit.exe are in the system folder. If bcdedit.exe isn't...

A double-sided DVD has 9.4 GB (twice the 4.7 GB of the usual, single-sided, DVD).

Advantages of thumb drives:
Capacities of 8 GB, 16 GB, and even 32 GB can be as low as $2 or so.
You can re-use...

I've found that some system utilities are missing or can't find data files when the system is corrupted. In my case, bootrec.exe doesn't have the data files needed to fix things, reagentc.exe is...

Was having trouble getting Windows to boot (see thread 186846), usually recovered by booting to recovery thumb drive or DVD, asking to repair boot issues, and then selecting exit to Windows. ...
